Interesting Thread.
Here is the first verse and Chorus from the original sheetmusic published in 1926. This would represent the authoritative lyrics that probably spawned some of the variations listed here and elsewhere. If I have time I'll did out the sheet music and provide the second verse and second chorus. The above link was to a first exposition of the song on our site, we reissued it with an article about novelty songs
in October, 1999:

THE LUNATIC'S LULLABY
Music & Lyrics by: Leslie Moore, Johnny Tucker & Edgar Leslie
Cover artist: Barbelle
Published 1926 by Edgar Leslie, Inc.

(four bar introduction, 4 bar vamp)
I'm up here in the bug house. My brain is in a rut.
My keeper says I'm crazy, but he is off his nut.
I'm just as sane as you are, and I can prove it too:
For when you hear my lullaby, you'll know I'm not cuckoo.

CHORUS: Oh! I was born at night one morn and the whistles rang boom boom.
I boil a cake and drink a steak when the mud pies are in bloom.
If six and six are nine, does ice come from a mine?
Then old Black Joe's an Eskimo, and pork's from porcupine.

A pig or cow can bark meow but a goldfish likes to sing.
I saw a frog swim up a log, but he fell and broke his wing.
I know that camels sail the sea, that we get honey from a flea,
That ev'ry horse can climb a tree on the road to Mandalay. CHORUS

Oh! me Oh! my, That's the Lunatic's Lullaby!
